Feature suggestion: Implement reboot to payload functionality

[noirscape]

As a suggestion, it would be handy to have the "Reboot to payload" feature that Atmosphere provides available within Lakka.

This would save users the time of having to use an external device to send a payload through RCM each time they want to shut down Lakka and in combination with Atmosphere could eliminate the need for the use of an external device in all situations that don't involve battery drainage or bugs.

Obvious request.
It's planned since hotboot got released.
